Vigil@nce - Linux kernel: buffer overflow via arcmsr_iop_message_xfer
November 2016 by Vigil@nce
This bulletin was written by Vigil@nce : https://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can generate a buffer overflow via
arcmsr_iop_message_xfer() on the Linux kernel, in order to trigger
a denial of service, and possibly to run code.
Impacted products: Debian, Linux, openSUSE, openSUSE Leap.
Severity: 2/4.
Creation date: 19/09/2016.
DESCRIPTION OF THE VULNERABILITY
The Noyau Linux product offers a web service.
However, if the size of data from the SCSI command is greater than
the size of the storage array, an overflow occurs in
arcmsr_iop_message_xfer().
An attacker can therefore generate a buffer overflow via
arcmsr_iop_message_xfer() on the Linux kernel, in order to trigger
a denial of service, and possibly to run code.
